Computer crashes while playing online Thread

I have gotten this problem lately. When I am playing online (and more often when I am keeping chat contact with someone, than not) my screen loses connection and speakers give a buzzing sound, and I am forced to shut down the comp by holding the power button on. When I have restarted the computer, a message comes up with some details. It mentions that I got the blue screen (though since my screen loses connection to the computer, I don't get an actual blue screen). When it does, this happens in 10 to 60 minutes after I start playing a game online. What is causing this?

only in online games ? that's weird
isn't it one game in particular ?

So far I've met this problem when playing TF2 online, as well as when playing LAN battles of Medieval 2: Total War. My brother had this problem when he played League of legends with my computer as well. I've yet to encounter this with other games though.

Sounds like you might need a new computer.
